How to test the application:
----------------------------

1.) run "ant dist" for creating the distribution file

2.) go to "build/dist" directory

3.) [optional] edit the "app-settings.xml" (there are some grammars registered
    already)

4.) run the application with required parameter - the xml file containing
    input sentences; there is one testing file in "tests/sentences"
    
5.) the output is written to the standard ouput (console); it can be redirected
    to a file (use second parameter or '>')
